Firearm Suppressor Baffle

ABSTRACT

A firearm suppressor baffle and related constructions. The baffle includes a forward disk portion, and a rearward tubular portion. The tubular portion acts to impede gas flow from an expansion chamber into the projectile&#39;s path of travel. This tube may be fitted with secondary baffles to create multiple gas-expansion chambers, accessible only through holes cut into the tubular protrusion or the baffles.

BACKGROUND OF THE INVENTION

The invention is related to flow reduction baffles and specifically tofirearms suppressor baffle design. A firearm muzzle suppressor orsilencer is a device mounted to the muzzle of a firearm which reducesthe sound report and muzzle flash of the firearm by impeding the flow ofthe gases exiting the barrel.

A typical suppressor is constructed from a cylindrical tube containing aseries of baffles separating chambers. These baffles may be constructedfrom one continuous piece of material (monocore), or a series ofdiscrete baffles (a baffle-stack suppressor). The first chamber andbaffle are commonly referred to as the blast chamber and blast bafflerespectively.

It is desirable to create a baffle that uses the chamber space moreeffectively, allowing for larger chambers, lighter suppressors, andimproved sound suppression. The present invention allows for the designof a suppressor having these desirable features while also being simplerto machine than contemporary monocore or baffle-stack suppressors.

BRIEF SUMMARY OF THE INVENTION

The invention in its simplest form is a baffle for use in a firearmsuppressor assembly. The baffle disk is formed to segment a suppressorbody into compartments situated linearly along the bore axis of theattached firearm. The baffle may also be placed as to form the front endcap (the end cap that is not proximal to the muzzle of the firearm) ofthe suppressor. A hole is placed concentrically with the bore of thefirearm to allow passage of the projectile. This hole need not belocated in the center of the baffle, in such a case where the suppressorbody is not a cylindrical tube or the body of the suppressor is notintended to be located concentrically with the bore of the firearm.

A tubular protrusion (which may be referred to as a blast tube tosimplify the description of the invention) extends from the baffle diskin the direction of the muzzle of the firearm. The internal diameter ofsaid protrusion is sufficient to allow the passage of the firearm'sprojectile. This protrusion extends concentrically with the bore of thefirearm a large portion of the distance to the firearm muzzle, orprevious baffle disk, as appropriate. The optimal length of saidprotrusion is dependent on many factors (including but not limited tothe number of total baffles, the calibre of the firearm, and theintended weight of the complete suppressor). The length of saidprotrusion is sufficient to create a chamber between said protrusions'outer diameter and the suppressor main body, said chambers' openingbeing towards the end of the suppressor attached to the muzzle of thefirearm.

Said disk and tubular protrusion may be described as constituting aprimary baffle.

The present invention also consists of a modification to said primarybaffle. The blast tube of the above baffle may be fitted with asecondary disk or cup (or multiple such disks or cups) that furthersegments the interior of the suppressor body into chambers. These disksmay be flat, or sloped or curved. Said disks may extend fully to thewall of the suppressor body, or they may extend only part way. Said cupsmay have their face that is located perpendicularly to the bore axisshaped like the above disks. Said cups are shaped such that they extendaway from the muzzle of the firearm and connect to either the end cap ofthe suppressor, a primary baffle (as described above) or the next cup ina stack of cups, similarly to a conventional suppressor baffle stack.

Hole are cut into the center blast tube of the primary baffle such thatgases may flow into the chambers formed by said secondary disks. In thisway, the benefits of a conventional baffle stack are attained with onlysimply constructed secondary disks.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows the firearm suppressor baffle in a rear perspective view.The baffle disk 11 is shown with the tubular protrusion 12 extendingaway from the disk in the direction towards the firearm. Said tubularprotrusion (referred to as the blast tube) is hollow and open on bothends. When assembled into a complete suppressor attached to a firearm,the end of the tubular protrusion 13 is proximal to the muzzle. When thefirearm is discharged and the projectile passes from the near end of thebaffle to the far end 14, a portion of the discharged gasses will notenter the blast tube 12 and instead expand into the chamber around it.In this way the report of the firearm is suppressed.

The baffle disk 11 is shown as flat and concentrically aligned with thebore axis. The baffle disk could be non-circular, irregularly shaped,slanted, conical, or have some combination of these features.

FIG. 2 shows a possible complete suppressor depicted in a cutaway view.The host firearm attaches to the suppressor via its barrel 21. Thebarrel is attached to the rear endcap 22 of the suppressor body. Saidendcap is affixed inside the suppressor outer body 23, in this case, atube. This suppressor is constructed with two of the present invention24 and 25, the second of which functions as the front endcap of thesuppressor 26. The baffle disks are attached to the suppressor body viaone of many methods (including threading, welding, and glueing). Thetubular portion of the invention creates a chamber 27 between thesuppressor body and the path of travel of the projectile. A similarchamber 28 is created in the frontward section of the suppressor. Whilethe projectile passes through and exits out the front of the suppressor31, the gases expand into these two chambers.

Some of the possible features of the invention are depicted. A slopedflange 29 acting to perturb airflow is connected to the first baffles'opening. A tiered set of steps 30 acting to perturb airflow is shownconnected to suppressors' barrel side end cap. The baffle disk need notbe flat nor attached to the tubular protrusion at 90 degrees, as shownin the second baffle 25.

FIG. 3 depicts a suppressor constructed more simply than the suppressorshown in FIG. 2. In FIG. 3, the barrel of the firearm 41 is attached tothe rear endcap 42 of the suppressor assembly. Said endcap is attachedto the suppressor main body 43. In this suppressor assembly, there isonly a singular instance of the present invention 44, which creates alarge interior expansion chamber 45, and also acts as the end cap of thesuppressor 46. Also shown in this figure is a simple ring construction47 for perturbing airflow attached to the baffle's tubular protrusion44.

FIG. 4 depicts a suppressor constructed using three secondary baffles54, 55, and 56 affixed to an blast tube 53. There is a space 52 betweensaid blast tube and the muzzle side suppressor end cap 51 sufficient toallow gasses to expand into the large chamber surrounding the blasttube. The baffle disk 57 attached to this blast tube acts as the frontend cap of the suppressor. Gasses that pass through the internal portionof the blast tube are allowed to expand into the three chambers createdby the secondary baffles via a number of holes 58 placed in the blasttube.

A firearm suppressor baffle constructed of a disk (or other shapefitted to a suppressor body) from which a tubular protrusion (the blasttube) extends; wherein: the baffle disk separates chambers within asuppressor assembly, a hole in the disk permits the passage of aprojectile, the disk being shaped in any manner that allows it to beconnected to the walls of the suppressor outer body; the tube defines anaxis concentric with the muzzle of a firearm along which a projectilecan pass, the space between the tubular protrusion and the suppressorouter body defines a chamber for the expansion of gasses, a gap betweenthe tube and any previous feature of the suppressor in the direction ofthe firearm's muzzle allows gasses to enter the chamber for theexpansion of gasses.
